HV Inverter Charger SMA Sunny Boy Storage 6kW SBS6.0-10 Single-phase

Product description

The SMA Sunny Boy Storage 6kW SBS6.0-10 HV Inverter Charger Monophase is the most powerful "battery inverter" in the Sunny Boy Storage-10 series. Designed for AC coupling, it allows the integration of high-voltage lithium batteries into new or existing photovoltaic installations (even with inverters from other manufacturers) to maximize self-consumption and ensure service continuity. It offers 6 kW (6 kVA) output, a maximum efficiency of 97.5%, IP65 enclosure, and multistring architecture with 3 independent HV inputs, providing superior flexibility for sizing and expanding the battery bank. It incorporates a Secure Power Supply (SPS) of 3.68 kW for emergencies and can add automatic backup for the entire home via external switching equipment.

Main features

• Nominal AC power: 6 kW (6 kVA) single-phase at 230 V; nominal output current 26 A; overload up to 7.5 kW (60 s).
• 3 independent HV battery inputs (multistring), parallelizable for large banks; easy integration in AC-coupled systems.
• Battery input: range 100–550 Vdc (Vnom 360 V), 10 A per input, 600 Vdc max.; total admissible I_SC 40 A.
• Efficiency 97,5 % (EU ~96.8%); transformerless topology and convection cooling (no fans).
• Native connectivity: WLAN and Ethernet/Speedwire, Webconnect and Modbus SMA/SunSpec, Modbus-RTU (RS-485), and CAN bus for battery.
• Safety and optimization functions: SMA ShadeFix (shade management) and ArcFix/AFCI (arc detection).
• 3.68 kW SPS for critical loads (manual switching) and option for automatic backup with external switch.
• IP65 enclosure, −25…+60 °C, 535×730×198 mm, 26 kg; typical noise level 39 dB(A); altitude up to 3000 m; RH 100%.
• SMA Smart Connected service for proactive monitoring and automatic notifications to the installer.

Advantages or benefits

• Autonomy and power: 6 kW continuous and HV architecture to cover night peaks and supply the home with high efficiency.
• True scalability: its 3 HV battery inputs (3×10 A) allow combining or expanding approved batteries, or paralleling them for greater capacities.
• Modernization without changes to PV: as an AC-coupled inverter, adds storage to existing installations without touching the string inverter.
• Service continuity: 3.68 kW SPS for emergencies; possibility of automatic “backup inverter” for the entire home with additional hardware.
• Connectivity and control: integration with SMA Energy Meter and Sunny Home Manager 2.0 for zero feed-in, load management, and e-mobility.
• Reliability and low maintenance: fanless design, IP65, and SMA electronics “Made in Germany”.

Purpose or applications

The SBS6.0-10 is suitable for homes with medium-high consumption and small businesses seeking a 6 kW HV inverter-charger for AC battery systems. Perfect for expanding already installed self-consumption systems, for projects with time-of-use tariffs, integration of heat pumps, DHW, or EV chargers, and for those who need a basic backup level with automatic switching option.

Technical specifications

Compatibilities

Direct (official) compatibility: HV lithium batteries approved by SMA (including the SMA Home Storage range); Sunny Home Manager 2.0 and SMA Energy Meter for feed-in control and load management; native integration with SMA inverters with Webconnect for power coordination.
